How do you know a thing? An old hat, a busted bicycle, a chair? Sometimes, you must leave it outside in the rain and sun for weeks and weeks. Or look at it upside down against the sky.
Or launch it. Then launch another thing. Then another!
Watch how it cracks, how it crushes. See how it flutters? Oh my, it shatters. Listen to the pops.
What is that juice? Is it green? Oh boy, is it smelly.
Thank you so much. Come back next week!
